Mathematical Modelling of Biomechanical Interactions between Backpack and Bearer during Load Carriage
Figure 7
The simulated pack interaction forces in the pack coordinate system mean ((solid red line)) one standard deviation (dashed red lines): (a) longitudinal pack force, (b) normal pack force (c) and lateral pack force, compared with measured data (mean (solid blue line) one standard deviation (dashed blue lines)), for six repeated trials for one subject (age: 28 yrs, weight: 71.8 kg, height: 178 cm). The average walking speed was m/s, and the pack load was 11.5 kg. The stance phase for the left limb is from 0 to 60%, and the swing phase is from 60% to 100%. The double support phase is from 0 to 10% and from 50 to 60%.
